An oscillating assembly comprises first and second opposed gudgeons rotatably mounted on a shaft, the gudgeons being connected by either a plurality of rods or the roller. An oscillation mechanism comprises a reduction transmission assembly having differently toothed input and output pulleys. A cam groove in an oscillation cam is engaged by one or more oscillation pin(s) connected to the gudgeons. An input drive pulley turns with the gudgeons, and an output pulley turns with the oscillation cam. An intermediate double-pulley has second and third pulleys on a common hub. First and second timing belts connect, respectively, the input pulley to the second hub pulley, and the third hub pulley to the output pulley. A currently preferred step-down ratio between the input pulley and the output pulley is about 391:1. ## Claims ### Claim 1 A system for oscillating a working roller disposed between first and second gudgeons slidably and rotatably disposed on a non-rotatable shaft, comprising: an oscillating assembly disposed for oscillation and rotation on said shaft; and an oscillation mechanism disposed for rotation on said shaft and connected to said oscillating assembly, wherein said oscillation mechanism comprises: at least one tie rod connecting said first and second gudgeons; at least one oscillation pin connected to said tie rod and extending radially inwards from said tie rod toward said shaft, an oscillation cam rotatable on said shaft and including a first timing element; wherein the oscillating assembly is oscillated by the oscillation pin in cooperation with the oscillation cam; and wherein said oscillation mechanism includes a reduction transmission having a plurality of timing elements rotationally connected in an arrangement to yield a desired rotation ratio between said oscillating assembly and said oscillation mechanism. ### Claim 2 (depends on 1) A system in accordance with claim 1 wherein at least one of said timing elements is selected from the group consisting of a conventional pulley having a continuous outward-facing groove surrounding a hub, which groove may be toothed; a conventional pinion gear; and a non-toothed roller. ### Claim 3 (depends on 1) A system in accordance with claim 1 further comprising at least one belt in said reduction transmission. ### Claim 4 (depends on 3) A system in accordance with claim 3 wherein said at least one belt is a toothed belt and wherein at least one of said timing elements is a toothed pulley engaged with said toothed belt. ### Claim 5 (depends on 3) A system in accordance with claim 3 wherein at least one of said belts is a non-toothed belt and wherein at least one of said timing elements is a non-toothed pulley engaged with said non-toothed belt. ### Claim 6 (depends on 1) A system in accordance with claim 1 wherein said timing elements are connected by a plurality of belts, and wherein said rotation ratio is governed by the respective diameters of respective of said timing elements. ### Claim 7 (depends on 1) A system in accordance with claim 1 wherein said oscillation mechanism is contained wholly within said oscillating assembly. ### Claim 8 (depends on 1) A system in accordance with claim 1 further comprising a plurality of bearings disposed between said gudgeons and said shaft. ### Claim 9 (depends on 1) A system in accordance with claim 1 further comprising an oscillation tubing sleeve surrounding said tie rod and extending between said first and second gudgeons. ### Claim 10 (depends on 7) A system in accordance with claim 7 wherein said oscillation mechanism comprises: an oscillation hub disposed on said shaft and rotatably supportive of said oscillation cam and engagable with said oscillating assembly and having a second timing element; a pulley hub supportive of third and fourth timing elements; a first timing belt connected to said first and third timing elements; and a second timing belt connected to said second and fourth timing elements. ### Claim 11 (depends on 10) A system in accordance with claim 10 wherein said first, second, third, and fourth timing elements and said first and second timing belts define said reduction transmission. ### Claim 12 (depends on 11) A system in accordance with claim 11 wherein the reduction ratio of said reduction transmission is about 391:1. ### Claim 13 (depends on 10) A system in accordance with claim 10 wherein at least one of said timing elements is a toothed pulley. ### Claim 14 (depends on 10) A system in accordance with claim 10 wherein at least one of said timing elements is a non-toothed pulley. ### Claim 15 (depends on 10) A system in accordance with claim 10 wherein at least one of said timing elements is a pinion gear. ### Claim 16 (depends on 10) A system in accordance with claim 10 wherein at least one of said timing elements is a smooth roller. ### Claim 17 (depends on 10) A system in accordance with claim 10 wherein all of said timing elements are toothed and wherein said reduction ratio is governed by the number of teeth on respective of said toothed timing elements. ### Claim 18 (depends on 10) A system in accordance with claim 10 wherein all of said timing elements are non-toothed and wherein said reduction ratio is governed by the diameters of respective of said non-toothed timing elements.
